Specific embodiment
As shown in Figure 1, a kind of wind farm group inside wind direction confirmation method, the wind direction gone out inside whole wind farm group by a kind of Algorithm Analysis based on wind direction at each wind power plant, to obtain the mutual wind direction relation of each wind power plant in wind farm group, and a table is built based on this relation record these influence relations, comprise the following steps that described.
Step 1, changes wind farm group coordinate, the wind power plant latitude and longitude coordinates in wind farm group is converted into simple two-dimensional coordinate and makes the two-dimensional coordinate in the first quartile of the coordinate system set up.
Assume that the wind power plant situation in wind farm group is as shown in Figure 2 in the present embodiment.
Step 2, judges wind power plant wind direction, confirms single wind power plant inside wind direction, after the wind direction inside each wind power plant is confirmed, draws the position of the outlet and inlet of each wind power plant, wind direction is carried out to wind farm group and is confirmed.
Wherein, single wind power plant inside wind direction confirmation method is as follows：
(1) blower fan coordinate is set, the latitude and longitude coordinates of blower fan is converted into simple two-dimensional coordinate and is made these two-dimensional coordinates in the first quartile of the coordinate system set up.
Wind direction is the positive direction of x-axis to two-dimensional coordinate from West to East, it is the positive direction of y-axis from south orientation north, angle a be with the angle of x-axis positive direction (0-360 °), the wind electric field blower is an array, and the row and file of the wind electric field blower array be parallel with x-axis with y-axis respectively.
(2) judge air intake position, judge blower fan at wind power plant air intake position.
Setting one angle parameter a0, the a0 are the important parameters for setting critical wind direction of the wind power plant in different air intake situations；Simultaneously, the wind direction for taking the blower fan at the minimum place of x, y-coordinate is a1, takes that x coordinate is maximum, the minimum place of y-coordinate blower fan wind direction is a2, takes x, the wind direction of the blower fan of y-coordinate maximum is a3, take x coordinate minimum, the wind direction of the blower fan of y-coordinate maximum is a4, specifically judges that step is as follows：
The parameter that gets parms a0, the parameter a0 can be analyzed acquisition to the history wind direction of wind power plant, air speed data, it is also possible to which artificial is configured in parameter setting part；
The wind direction of wind power plant four wind direction datas a1, a2 in corner, a3 and a4 and anemometer tower is analyzed, the accuracy of this blower fan everywhere is detected, needs to be substituted from the data of neighbouring border blower fan if inaccurate；
Decision method is as follows to be judged to the air intake position of wind power plant according to different wind directions：
If the blower fan at S (x, y) expression selection (x, y) coordinates is used as blower fan at the inlet air point of wind power plant,
When 0<a1<During a0, then S (xmin ...) (choosing all blower fans at x minimums)；
Work as a0<=a1<During=90-a0, then S (x min ...) and S (..., ymin)；
Work as 90-a0<a1<When=90, then S (..., ymin)；
When 90<a2<During 90+a0, then S (x min ...)；
Work as 90+a0<=a2<During=180-a0, then S (x max ...) and S (..., ymin)；
Work as 180-a0<a2<When=180, then S (x max ...)；
When 180<a3<During 180+a0, then S (x max ...)；
Work as 180+a0<=a3<During=270-a0, then S (x max ...) and S (..., ymax)；
Work as 270-a0<a3<When=270, then S (..., ymax)；
When 270<a4<During 270+a0, then S (..., ymax)；
Work as 270+a0<=a4<During=360-a0, then S (x min ...) and S (..., ymax)；
Work as 360-a0<a4<When=360, then S (x min ...).
If some borderline blower fans are not because failure and other reasons work, then closest to its non-border blower fan, first Fans of lower wind direction i.e. in wind power plant totality wind direction, if influenceed by wake effect, need to be judged according to the angle of its neighbouring wind power plant border blower fan.
(3) internal wind direction is determined：Each blower fan inside wind power plant is analyzed, a relation table on each wind turbine wind direction in wind power plant inside is obtained, based on the relation table, wind direction inside whole wind power plant is drawn out.
With when 0<a<As a example by 90：
If wind direction difference critical value be β, coordinate critical value be γ, it is considered to now under blower fan wind direction three possible blower fans,
Now understand that wind necessarily first passes through blower fan 0 according to wind direction, if wind direction is ε (0 at the blower fan 0 for now measuring<ε<90),
Work as ε<During=a0, then the wind direction that can analyze blowing machine 1 is necessarily influenceed by blower fan 0, i.e., they are on a distinguished and admirable field wire, and the wind direction of remaining blower fan is little with the wind direction relation of blower fan 0, and the relation can be added in wind direction relation table；
Work as ε>During=90-a0, then the wind direction that can analyze blowing machine 2 is necessarily influenceed by blower fan 0, i.e., they are on a distinguished and admirable field wire, and the wind direction of remaining blower fan is little with the wind direction relation of blower fan 0, and the relation can be added in wind direction relation table；
Work as a0<ε<During 90-a0, whether blower fan 0 is accomplished by being further analyzed with blower fan 5 on a distinguished and admirable field wire.It is that β and coordinate critical value are γ hereinbefore to introduce wind direction difference critical value, wind direction difference critical angle β is used to judge both sides relation by the wind direction differential seat angle of blower fan at two, and coordinate critical angle gamma is then for judging both sides relation with the relation of blower fan 0 by the differential seat angle of blower fan at two；
If the coordinate of blower fan 5 is (x5, y5), the coordinate of blower fan 0 is (x0, y0), wind direction at blower fan 5 is ε 5, then when data between the two meet following formula 1 and formula 2, just it is considered as blower fan 5 and blower fan 0 on a distinguished and admirable field wire, both corresponding numberings in wind power plant is recorded in wind direction relation table；
|ε5-ε|≤β (2)
If during condition when blower fan 5 can not simultaneously meet formula (1) and formula (2), needing to be analyzed the data at blower fan 6 and blower fan 7 the two blower fans；
WhenWhen, it is necessary to be analyzed according to the formula 1 and formula 2 to the data of blower fan 6, if setting up by the relation record of blower fan 0 and blower fan 6 in wind direction relation table；

By analysis, it can be deduced that the position of the outlet and inlet of each wind power plant, the angle of each air intake position does not have too big difference, and the angle of same each air-out position there will not be too big difference.Wind power plant can be so defaulted as unified air intake angle and air outlet angle, and the confirmation of wind direction just can be carried out to wind farm group.
The unified air intake angle of wind power plant and air outlet angle analysis method are as follows：Assuming that have m Fans on the air intake border of wind power plant, and wind direction is respectively α 1, α 2... α m at blower fan, the weight of wind direction is respectively i1, i2...im, then can obtain wind power plant enters mean wind directionAs shown in Equation 3：
Assuming that there are a n Fans on the air-out border of wind power plant, and wind direction at blower fan is respectively β 1, β 2...... β n, and the weight of wind direction is respectively j1, j2......jn, then can obtain the wind power plant goes out mean wind directionAs shown in Equation 4：
Step 3, confirms wind power plant relation, and the data according to anemometer tower judge the overall substantially wind direction of wind farm group, so as to judge order of the wind by each wind power plant, recursion analysis are carried out further according to the order successively downward wind direction, untill satisfaction is required.
Assuming that the wind power plant of lower wind direction is followed successively by wind power plant 1, wind power plant 2, wind power plant 3...... in wind farm group, then need for the wind power plant 1 to go out mean wind speedThe mean wind speed that enters with lower wind direction each wind power plant judged successively, until there is wind power plant to meet to require or without wind power plant untill；
The center of each wind power plant is taken as its analysis position, coordinate is respectively (xz1, yz1), (xz2, yz2) ..., it is θ to set the difference critical angle of field wind direction, and field coordinate critical angle is λ, and analysis method is illustrated by taking the wind power plant 1 and the wind power plant 2 as an example；
When the wind power plant 1 and the wind power plant 2 meet following two relational expression 5 and formula 6, represent two most of parts of wind power plant on the same distinguished and admirable field wire of wind farm group.
When the data of wind power plant 1 and wind power plant 2 meet two formulas (5) above and (6) simultaneously, by both relation records wind direction relation table on the scene；If can not simultaneously meet above-mentioned formula (5) and (6), then the data of wind power plant 1 and wind power plant 3 are analyzed, the like, untill meeting and requiring.
Step 4, confirms wind farm group inside wind direction relation.
